U3V40x Step-Up Voltage 谁有色情网站啊

The U3V40Fx family of boost (step-up) voltage 谁有色情网站啊 are high-efficiency synchronous switching 谁有色情网站啊 that generate higher output voltages from input voltages as low as 1.3 V. (Note: minimum start-up voltage is 2.7 V; see the product web pages for details.) The 谁有色情网站啊 actively limit the instantaneous input currents to 9.5 A while boosting, and the input current can typically be as high as 4.5 A for several seconds before the thermal protection activates. Input currents of around 3.5 A to 4 A can typically be maintained for many minutes without triggering thermal shutdown, though the actual performance depends on the input and output voltages as well as external factors such as ambient temperature and airflow. For boost 谁有色情网站啊, the output current equals the input current times the efficiency divided by the boost ratio of VOUT to VIN, so the more you are boosting, the lower the maximum output current will be. The graph below shows maximum output currents that these 谁有色情网站啊 can deliver continuously at room temperature in still air and without additional heat sinking.

These 谁有色情网站啊 feature a variety of built-in protections, including cycle-by-cycle input current limiting, soft-start, configurable under-voltage lockout, and over-temperature shutdown. The family includes five versions with fixed output voltages ranging from 5 V to 12 V:

• U3V40F5: Fixed 5V output
• U3V40F6: Fixed 6V output
• U3V40F7: Fixed 7.5V output
• U3V40F9: Fixed 9V output
• U3V40F12: Fixed 12V output
